Bard LV and RV Controllers
R-410A
Dual Capacity: System fluctuates between two cooling capacities. The HR Series High Sensible system operates at ranges from 3.5 ton to 5 ton, based upon need and peak efficiency.
Reverse Airflow: Peak performance low side air discharge directs the cooler air used for electronics and equipment cooling at floor level where it is needed. The heat from the shelter is pulled back into the FUSION-TEC from ceiling level to be exhausted to the outside, or integrated into the mechanical cooling system.
Free Cooling Unit: All units are designed to optimize any free cooling outdoor air opportunities. The FUSION-TEC features positive seal dampers to eliminate unwanted air migration. Peak operation is constantly monitored and deviations result in an alarm. (Free cooling may be disabled via software when needed.) As a safety design, an air quality switch has been integrated into the system to keep dirt and debris out of the building .
Logic Board: System control panels are equipped with PLC Logic Boards that allow multiple unit operation with a single controller. Unit connection to the LV controller is accomplished with 2 wire shielded cable with drain (ground).
Advanced Unit Diagnostics: Whether connected to the TEC-EYETM diagnostic tool, or just viewed
from the shelter control, the system PLC Logic Board is able to display stored alarms and easy to read diagnostic information.
Orphan Mode: System is designed to run independently if communication to the LV controller is lost, meaning that cooling can be provided even if the controller or wiring fails.
Airflow Switch: All systems feature an airflow switch to monitor blower operation. Settings are field adjustable with alarm signal.
Dirty Filter Switch: All systems include an airflow switch to monitor pressure drop across the unit filter. This will indicate when a filter change is needed. Settings are field adjustable with alarm signal. An indicator light is located on the outside of the FUSION-TEC.
High Pressure Transducer: A high pressure transducer is used for advanced diagnostic features including an alarm signal when condenser coil cleaning is needed.
Low Pressure Transducer: A pressure transducer is used for advanced diagnostic features and indication of refrigerant loss. Combined with other sensors, the FUSION-TEC will constantly display superheat readings.
High Efficiency Indoor Blower: Using the latest technology DEC Star® fan design, the
FUSION-TEC achieves peak CFM airflow rates with the lowest energy usage possible.
High Efficiency Outdoor Fan Motor: The FUSION-TEC uses a high efficiency ECM fan system to provide air through the condenser coil. By varying the fan speed, the system is able to provide

TMFree Cooling Economizer and Air Conditioner
The FUSION-TECTM has been designed specifically to optimize free cooling opportuni-ties. By implementing a reverse-airflow design, productive outdoor air for free cooling is brought into the system from the lower portion of the chassis. The heat in the shelter is exhausted out of the top of the chassis which completely eliminates any possibility of recirculating hot exhaust into the cool air entryway. When outdoor air is not productive for free cooling, the FUSION-TEC system has a fully flexible mechanical cooling opera-tion that operates at an IPLV of 15.7, and also satisfies the D.O.E.'s 11.0 EER efficiency requirements.

Product Design Features
Counterflow HR Series in the Standard Wall Mount Footprint
The FUSION-TECTM counterflow unit uses the advantages of having a high supply opening to draw heated
air from the ceiling level, and discharge cooler air where it is needed the most, at equipment and floor level. This is done using the standard wall mount footprint that has been used for years in the shelter and equipment cooling industry and requires minimal or no wall modifications to replace existing wall mount cooling equipment. This is accomplished by reversing the airflow through the existing wall openings.
An Energy Saving Economizer with Mechanical Cooling
By design, the Bard FUSION-TECTM HR Series counterflow unit has a built-in free cooling economizer with
separated intake and exhaust air paths. Using separate cold air intake and heated room air exhaust openings dramatically reduces the recirculation effect of room air being discharged from the unit and drawn back into the fresh air intake. This makes economizer operation as efficient as possible and allows for proper intake airflow temperature measurement.

Copeland UltraTech Compressor
The Copeland Scroll UltraTech compressor offers a better means of powering air conditioning systems. Building on established scroll technology, the Copeland Scroll UltraTech compressor provides superior humidity control, greater efficiency and quieter operation, providing unsurpassed reliability and performance along with increased comfort and reduced energy bills.
Modulating compressors provide precise temperature control, lower humidity and greater energy efficiency in comparison to fixed capacity compressors. The Copeland Scroll UltraTech compressor modulates between two capacity settings, 67% and 100%. Two internal bypass ports enable the compressor to run at 67% part-load capacity during times when only part-load cooling is needed. When demand increases, the modulation ring is activated, sealing the bypass ports and instantly shifting capacity to 100%. Running for longer periods at part-load capacity (67%) lowers the humidity inside the building and allows the HVAC system to operate more quietly. With the redesigned Copeland Scroll UltraTech compressor, the VA load is reduced to an expected range of 2-5 VA.

Dirty Filter Switch
All unit models utilize an adjustable dirty filter pressure switch to indicate when the filter needs to be changed. The dirty filter switch measures the pressure difference on both sides of the filter through tubing routed to the blower and vent areas of the unit. When pressure increases to a pre-set measurement in the switch, an alarm signal is sent to the unit programmable logic board, then to the LV controller. The controller energizes a set of normally open contacts. A LED light is also installed on the exterior cabinet surface to indicate a filter change is required.
Filter Replacement Light
A light is provided on the exterior of the unit that illuminates when the unit filter needs to be replaced. The light is located on the front left side of the cabinet. When the alarm signal for a dirty filter is reset through the LV1000 controller, the light will no longer be illuminated.
Indoor Blower Operation Pressure Switch
All unit models will utilize an indoor blower operation switch to indicate when blower airflow is not adequate for unit operation due to a failed evaporator blower motor or other mechanical airflow issue. The switch measures the pressure difference on both sides of the blower partition through tubing routed to the blower inlet and outlet areas of the unit. When pressure decreases below a pre-set measurement in the switch, an alarm signal is sent to the unit programmable logic board, then to the LV controller. The controller energizes a set of normally open contacts.
Compressor Control Module
A low voltage monitoring device is used to monitor power and indicate a low incoming voltage situation caused by inadequate shore power or generator operation. The monitoring device protects the unit against compressor contactor “chatter” and reverse compressor rotation during these situations.
Return Air Temperature Sensor
All unit models have a return air temperature sensor installed for operation in “orphan” mode. The return air temperature sensor is also used for indoor temperature averaging with the use of the LV controller. The return air sensor is located in the upper part of the return opening in such a way that it is exposed to the entering airstream. Information is received by the unit logic control board using a 10K resistance signal. An alarm will be sent to the LV controller if the return air temperature sensor is disconnected.
Supply Air Temperature Sensor
All unit models use a supply air temperature sensor. By monitoring the air temperature leaving the supply opening, the unit logic control board is able to monitor the air entering the shelter. Information is received by the unit logic control board using a 10K resistance signal. An alarm will be sent to the LV controller if the supply air temperature sensor is disconnected.
Outdoor Air Temperature and Humidity Sensor
All unit models use a outdoor air temperature and humidity sensor. Using the sensor, the unit logic control board is able to monitor the outdoor air temperature, humidity and dew point. When conditions are acceptable for bringing in cooler outdoor air, the unit logic control board will allow economizer operation. The unit software can be set to operate economizer in Dry Bulb, Humidity %RH or dew point. An alarm will be sent to the LV controller if the supply air temperature sensor is disconnected.
Compressor Crankcase Heater
All unit models have a crankcase heater installed as standard. The
crankcase heater is a belly band style heater encircling the base section of the compressor housing. When the unit is not in operation, the crankcase heater is a precautionary measure to prevent compressor oil migration, deter oil and refrigeration from mixing and avoid refrigerant condensation.
Care must be used when servicing the unit to avoid being burned by the belly band attached to the compressor base. Always disconnect power when servicing this area of the unit.
Economizer Air Intake Quality Dust Sensor
All unit models include a dust sensor to monitor the outdoor air quality entering the economizer damper area. When conditions are unacceptable due to particulates in the air including farm field debris, highway dust and dirt, or other particulates, the economizer is disabled.
The sensor monitors dust density by using an optical system The optical portion of the sensor uses a light-emitting diode and light detector. The sensor is shipped pre-set, but may be adjusted for less or more sensitivity.
High Pressure Transducer
All unit models have a high side pressure transducer. The transducer will be used for system monitoring of high side system pressures. This information will be used to indicate when outdoor coil cleaning is necessary based on outdoor conditions and system pressures. When high pressure increases beyond a pre-set measurement when compared to outdoor temperature stored in the unit programmable logic board, an alarm signal is sent from the unit programmable logic board to the LV controller. The controller energizes a set of normally open contacts to indicate abnormal high system pressure. The high pressure transducer also controls the outdoor condenser fan and motor to increase outdoor airflow during high outdoor ambient conditions. Superheat is displayed through the TEC-EYE diagnostic tool.
Low Pressure Transducer
All unit models have a low side pressure transducer installed on the suction line between the evaporator coil and compressor. The transducer is used for system monitoring of low side system pressures. This information is used to indicate a loss of system refrigerant. When low pressure drops below a pre-set measurement stored in the unit programmable logic board, an alarm signal is sent from the unit programmable logic board to the LV controller. The controller energizes a set of normally open contacts to indicate abnormal low system pressure. When a loss of charge is measured, the LV controller energizes a set of normally open contacts to indicate refrigerant loss and that the unit needs to be serviced. The low pressure transducer is also used for operation of the eletronic expansion valve (EEV).
High Pressure Safety Switch
All unit models have a high side pressure switch as a safety device. This device is connected to a safety rated set of contacts, and operates if high system pressures reach an unacceptable level. When activated, the unit will shut down compressor operation immediately. After a predetermined time, the unit will attempt to restart. If the switch is activated during the restart, compressor operation will lockout, and an alarm signal will be sent to the LV controller. This is a safety device that disables unit operation at a high refrigerant pressure. It is also used to protect unit components including the electronic expansion valve and compressor. Never disable the high pressure safety switch. Activation of the switch normally indicates the unit needs to be serviced.
Field-Installed Hard Start Kit SK-118 (Optional)
All unit models have a hard start kit available for field installation. The hard start kit may be used to provide additional torque for compressor startup. A relay is provided to energize a start capacitor during the initial starting of the compressor. When the starting winding voltage increases to a set value in the relay, the start capacitor is de-energized.
Freeze Stat Evaporator Coil Protection
All unit models include a freeze stat connected to the evaporator coil to avoid coil freeze up. This sensor, when activated, allows blower operation without compressor cooling until coil temperatures are above freezing. Once below freezing, normal unit operation resumes.

Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.
Based on 75°C copper wire. All wiring must conform to the National Electrical Code and all local codes.
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310 for power conductor sizing.
CAUTION: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to Note 8 of Table 310 regarding Ampacity Adjustment Factors when more than three current carrying conductors are in a raceway.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in accordance with the National Electrical Code and all local codes.
The FUSION-TECTM HR Series unit is able to operate in a dehumidification mode when the humidity level
reaches 80% RH. By running the unit at a lower blower speed, latent capacity is increased and water is removed from the shelter indoor air.
